Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing large-scale precision sheet metal structural parts, in particular to a secondary convenient positioning device for marking both sides of a workpiece. Background Art

[0002] When manufacturing sheet metal components with high precision requirements, conventionally, while laser cutting the sheet material for blanking, marking lines are made on the sheet surface, and these position-accurate marking lines are used to ensure the position accuracy of the mutual assembly of workpieces. However, mainstream large-scale laser cutting machines in production do not have the function of double-sided marking simultaneously. Therefore, in most cases, only one side with important precision marking lines or more marking lines can be selected for marking during cutting, while the marking lines on the other side are discarded. If the marking lines on the other side are required, the workpiece that has been cut and marked on one side can only be flipped, and then secondary marking is carried out on the other side.

[0003] Currently, a relatively practical method to solve the above problems is as follows: Lay a steel plate with a thickness similar to that of the workpiece and an area that can cover the workpiece contour in the cutting area, spot-weld several points on each side of the steel plate to the workbench to prevent the steel plate from moving, then start the laser program, cut out the contour that conforms to the flipped workpiece on the steel plate, take out the intermediate sheet material, then place the workpiece completed for the first time in the above contour, and then complete the secondary marking. Since the marking subroutine and the contour cutting subroutine originate from the same mother program, the coordinate positions of the marking lines can be accurately repeated on the outer contour of the workpiece.

[0004] The above method can meet the requirement of double-sided marking of workpieces, and the position accuracy can also meet the high-precision level of sheet metal parts. However, the above method still has obvious disadvantages and deficiencies. Among them, the waste of raw materials is serious, and when there are many types of workpieces and the quantity of single-piece or batch is small, waste will occur. Content of the Utility Model

[0031] Specifically, the laser cutting machine tooth table 1 has a unique tooth structure. This design can effectively clamp and fix various workpieces, thereby ensuring the stability and accuracy of the marking process. On both sides inside the tooth table, magnetic seats 2 are respectively fixed. This design greatly enhances the stability of the workpiece on the tooth table, preventing any unnecessary movement during the marking process. On the right side of the top of the tooth table, a laser cutting head 3 is equipped. It can precisely control the emission of the laser, thereby realizing high-precision cutting and marking of the workpiece. The top wall of the tooth table is connected with a plurality of tooth blocks 4. These tooth blocks cooperate with the magnetic seats 2 to jointly achieve precise secondary positioning of the workpiece, avoiding marking errors caused by position deviation. On the top wall of the magnetic seat 2, a magnetic switch button 7 is installed. This switch button can control the fixation and release of the workpiece. When marking the workpiece, the workpiece can be placed on the magnetic seat and fixed by operating the magnetic switch button. After the marking is completed, simply operate the magnetic switch button 7 to easily release the fixation of the workpiece. Behind the laser cutting machine, a preset positioning baffle 10 is provided. Fastening screws 15 are inserted through the inner wall of the baffle. These screws can firmly connect the baffle to the tooth table, forming a stable fixing structure. The workpiece 5 to be marked can be placed on the top of the baffle, which can ensure the accuracy of the marking position. At the same time, a first magnetic attracting surface 9 and a second magnetic attracting surface 11 are respectively provided on the right side and the rear side of the magnetic seat 2. These two magnetic attracting surfaces can achieve precise grasping and stable placement of the workpiece, further ensuring the stability and accuracy of the marking process, thereby greatly improving production efficiency, optimizing the production process, and reducing production costs.

[0035] Specifically, the spring washer 16 and the flat washer 17 reduce the rotational damage of the fastening screw 15 to the magnetic base 2, and the inclined surfaces 18 provided on the outer wall of the magnetic switch button 7 in a circumferential manner facilitate the rotation of the magnetic switch button 7.

[0036] Working principle: The laser cutting machine's pointed tooth table 1 has a pointed tooth structure, which can effectively clamp and fix the workpiece to ensure the stability of the workpiece during the marking process. Inside the laser cutting machine's pointed tooth table 1, magnetic bases 2 are firmly fixed on both the left and right sides. This design enables the workpiece to be placed more stably on the pointed tooth table during marking. On the top right side of the laser cutting machine's pointed tooth table 1, a laser cutting head 3 is carefully set up. This is the key component for marking and can accurately complete the marking task on the workpiece. In addition, to further improve the positioning accuracy, a plurality of tooth blocks 4 are fixedly connected to the top wall of the laser cutting machine's pointed tooth table 1. These tooth blocks can cooperate with the corresponding structures on the magnetic base 2 to achieve precise secondary positioning. On the top wall of the magnetic base 2, a magnetic switch button 7 is fixedly installed. This is an important component for controlling the suction and release of the magnetic base, and through it, the fixation and release of the workpiece can be conveniently controlled. A preset positioning baffle 10 is also provided at the rear side of the magnetic base 2. The front side of the inner wall of this baffle is threadedly penetrated with a fastening screw 15. This can enable the workpiece to remain in a fixed position during the marking process and avoid affecting the marking quality due to vibration or movement. The front end of the fastening screw 15 is threadedly connected to the rear side of the magnetic base 2, forming a stable fixed structure with the preset positioning baffle 10, further improving the positioning accuracy. On the top of the preset positioning baffle 10, the workpiece 5 to be marked can be placed. In this way, the workpiece can remain in an accurate position during marking. To facilitate the placement and removal of the workpiece, a magnetic attracting surface one 9 is provided on the right side of the magnetic base 2. This magnetic attracting surface can adsorb the workpiece, so that the workpiece will not slide or shift during the marking process. At the same time, a magnetic attracting surface two 11 is also provided at the rear side of the magnetic base 2. These two magnetic attracting surfaces can cooperate with the workpiece to achieve precise grasping and stable placement of the workpiece.
